Yes, I have issues, who does not?
Mine are with the G-code slicers. Nope, I am not crazy, just issues...
So when I export some of my creations from Freecad in *.st or *.obj, etc, then upload into Merlin it is warning me the object is not Manifold (watertight), and the slicing goes bananas, more or less, some I manage to print with some errors that I can neglect, but some, hey, the slicer would not even slice it, at all.
I need to understand what the problem is, where in thee FreeCad I must go to fix that and how.
Alos I need to understand if anybody else here has similar problems, and whit what programs (both ends, designing and slicing) and how do you sort that thing out?
Are some non free programs more unlikely to issue such error? Like Inventor or Blender or else?
